I suspect it's that and so much more! There's a huge science aspect to it now; and every year there's new pesticides, new seed varieties, crop-rations, yield techniques, etc. Not to mention the huge complicated business and tax bureaucracy that is modern farming. I'm sure this is only a small slice which is why it would be great to see more.

What I don't have even a sense of is how much of a daily concern a lot of this is or if it's a once-a-year kind of thing, or how much of it impacts somebody who "only" farms to support his family and may only have 1-2 workers versus hundreds.
